After a friends iphone 4 was stolen this weekend i have a few questions about the passcode options on a iPhone 4s. These options should seem obvious for Apple to implement but I don't think they are available: 1. I would prefer not to have to enter my passcode to unlock the phone for use, but instead require a passcode to change settings. 2. I would prefer a passcode to be required to shut off the phone Can this be done? Here's why - For those who can't stand having to input the passcode to unlock the phone, it would be nice to require a passcode to change the settings - this would prevent a thief to be able to quickly change the location services to off if they stole your phone. In addition, it should require a passcode to shut off the phone. This would mean a thief could not turn off the phone if your passcode option was activated, and they would be carrying a live phone that is still transmitting to the network which would be easily tracked via "find my phone". Right now it's too easy for thieves just to shut off the phone if the passcode option is activated and you are screwed. Wouldn't this seem like an obvious thing for Apple to implement?
